Where to get a relacement diffuser sphere for Minolta Autometer IV F?

[Rob-F]

I lost mine on a trip. It fell out and I didn't know until later. Does nayone know where to order it? I don't see them on eBay, Amazon, B&H. And I can't find a website to order one from Minolta. Are they even making photo gear any more? The only spare parts I see are for copiers.
